NodeBB connection has been lost, attempting to reconnect

Hi,
I paid somebody to install nodebb for me and all was going fine, i had a subdomain setup on my site so it would point to my vps with nodebb installed on it. Everything was fine until I tried to post another post and It told me that connection had been lost. I've tried restarting it multiple times and it still won't work.

I also think it was MongoDB as well because I noticed that the database was set to "0" (default MongoDB on NodeBB setup) and when I changed it to the nodebb database it was as if it was default. Very frustrating but considering the forum was relatively new, not much was lost.

@julian said in NodeBB instalation - centOS:
@Adam-Poniatowski Which page is that? We can get it resolved on the docs...
Oh I meant @JaredBusch tutorial, it is just the one point that is (sort of) obsolete, but one can add that to the mongod.conf file. The nodebb docs is fine. The only thing I can suggest, is to note down, that it is assumed that selinux is either permissive or disabled. in https://nodebb.readthedocs.io/en/latest/installing/os/centos.html
And maybe add @JaredBusch semanage commands there as well
@Shard Centos 7.3, it is full systemd, hence mongod does not install/copy anything into that folder. one can still use it, but its just a drag at this point. Hacking a systemd system into a systemv... I got accustomed to the change.

It is taking me some time - mostly because I'm not familiar enough with NodeJS / NodeBB.
Some observations:
Took a while to get the ./nodebb setup routine to work - had to do it first for MongoDB and then for Redis and then combine the two files and restart (redis / mongodb nodejs files do not get installed on the npm install command).
Then got stuck with launching multiple processes on reboot with systemd. Gave up on that and just used a crontab @ reboot line to run a shell script. Need to figure out how to restart / reload processes seamlessly.
Found some issues with socket.io and spdy - did not investigate, disabled spdy on nginx.
Found some issues with the 0.7.0 branch and upgraded to master 0.7.1 and found that much more stable. But these were plugin related - sections, adsense - dropped them both.
Made the mistake of setting the production flag in the environment variable NODE_ENV.
As of now, have a test site running persona, notifications plugins on a distributed setup - NFS / REDIS / MONGO DB on one server and a barebones NODEJS + NGINX/SSL on another.
Seems stable for now on a test setup on https://devlib.org will give it a day or two while I play around with the templates / plugins and watch memory usage, before I go through another effort to set the autoscale / loadbalancer up.
@baris @julian @psychobunny - I really like what I see so far. Well done. If all goes well with the setup / eval, I will be dropping you guys an email to see if I can fund some development.
